It's wrong to assume that everybody goes by the same chart. There are many different philosphies and many different means of determining it. I think there's only a few teams that actually use sabermetrics in their decision making processes, whether that be for players or game situations.
I don't know if the Royals use the sabermetrics system, or your system. Even if they used your system and lost, that wouldn't be a condemnation of your total system, it would be a single example. I would counter that the A's, Toronto, and the BoSox use sabermetrics and have shown positive results.
